Kornicker Glacier () is a glacier flowing northeastwards from the cirque bounded by Mounts Liptak, Southwick, Milton and Mullen in southern Sentinel Range, Ellsworth Mountains in Antarctica. The glacier merges with the terminus of southeast-flowing Thomas Glacier as both glaciers emerge from the range. Named by US-ACAN (2006) after Louis S. Kornicker, research zoologist, Department of Invertebrate Zoology (Crustacea), National Museum of Natural History, Smithsonian Institution, 1964-2006; Board of Associated Editors, Antarctic Research Series, American Geophysical Union, 1978-90.
